My invention relates to a combined computing, and listing machine, thesame being particularly adapted for use in connection with a weighingmachine or scale, such as is ordinarily used in stores and shops forweighing comparatively small quantities of commodities, such as meat,butter, sugar,'

tea, coffee, and like articles of household use.

This application is a division of an application filed by me April 21,1913, Ser1al No. 762,544, on a combined computing, indicating, andadding scale.

The principal object of my invention is I to produce a comparativelysimple mechanism for adding up and totalizing various ing drawings, 10designates a suitable housing, preferably constructed of sheet metal andwithin which the operating parts of my improved computing machine arelocated.

Arranged in the upper portion of this housing is a series of flat rings11 provided "with notched peripheries, said rings being arranged side byside and forming a part of the weighing mechanism with which my improvedcomputing machine is associated,

and for a more detailed description of this.

Weighing mechanism and notched disks, reference may be had to mycopending application hereinbefore referred to.

Loosely mounted in suitable hearings in the upper rear portion of thehousing 10 is a shaft 12 in which is formed a groove 13 g and mountedfor sliding movement on this shaft is a hub or collar 14 provided with akey or feather which occupies the groove 13. Looselymounted on thecentral portion of this hub or collar are three horizontally disposedand forwardly projecting arms 15, the forward ends of which are providedwith upwardly projecting pins 16 which are adapted to engage the notchesof the rings 11 when the forward ends of the arms 15 are elevated.Projecting forwardly from the forward ends of these arms 15 are shortfingers 17 which are adapted to engage beneath fingers carried by aseries of racks hereinafter described.

Loosely mounted on one end of the hub 14 is a rearwardly projecting arm18 to which is connected one end of a rod 19,"

which slides through a bearing formed in one of the side walls of thehousing 10, and said rod being operated in any suitable manner forshifting the hub 14 upon the shaft 12.

Where my improved calculating machine is-combined with a weighingmechanism, the

rpd l? is actuated during the operation of hub- 14 is a bell crank 20and seated in the horizontally disposed arm thereof is a pin 21 whichoverlies the arms 15. Fixed to the upwardly projecting arm of this bellcrank is a pin 22 to which is attached the upper ends of threeretractile springs23, the lower ends of which are attached to the arms15. Arranged within the upper front portion of the housing 10 is a rod24, and loosely mounted therein are the ends of three rearwardlyprojecting frames 25, forward portions of which occupy positionsimmediately in front of the forward ends of the arms 15. Formed on therear ends of these frames 25 are rearwardly projecting fingers 26, thesame being arranged in sets of three each, and the rear ends of thesefingers overlie the three fingers 17 projecting forwardly from the arms15.. (See Fig. 3.)

Loosely mounted on the shaft 24 and extending rearwardly therefrombeneath the frames25 is a series of horizontally disposed arms 27 theundersides of which are provided with shoulders 28 which are adapted toengage the teeth of segments hereinafter described.

The first three of these arms 27, designated by a, b, c, are utilized inconnection with the accumulating printing mechanism of my improvedmachine, while the remaining arms are utilized only in connection withthe total adding mechanism hereinafter described.

The arm a of the series 27 is connected to the frame a of the series 25,so as to move vertically therewith, and the remaining two frames of theseries 25 are slotted vertically to permit this movement withoutaffecting said arm a.

The arm 6 of the series is connected to the intermediate frame I) tomove vertically therewith, and the other two frames being slotted topermit such'vertical movement; likewise the arms a of the series 27 isconnected to the frame 0- of the series 25 to move vertically therewithand the other two frames are slotted to permit such vertical movement.

short rod 31 which extends beneath the rear ends of all of the arms 27.Fixed to the shaft 29 is ashort crank arm 32 to which is pivotallyconnected the upper end of a link 33.

Arranged near the central portion of the housing 10 and journaled insuitable bearings in the side walls thereof is a shaft 34, and looselymc'inted thereon immediately below the arms 27 is a series ofsubstantially S-shaped segments 35. There is one of these segments foreach arm 27, and formed integral with the first three of these segments,and which first three correspond with the arms-a, b, and c, of theseries 27, are forwardly projecting arms 36 in the upper edge of each ofwhich is formed a series of 10 teeth 37. These teeth are formed on theedge of a circle which is eccentrically arranged with respect'to theaxis formed by the shaft 34,'the purpose of which arrangement willhereinafter be more fully set forth.

Under normal conditions, the first teeth of each series are positioneddirectly behind the correspondin shoulder 28 of the corresponding arm 2It is not necessary to provide these teeth on the segments beyond thefirst three, as a single tooth which is normally positioned directlybehind the corresponding shoulder 28, is sufficient to normally holdthese remaining segments in proper position.

Formed integral with the upper portions of all of the segments andextending downwardly and rearwardly are curved racks 38 which have tenteeth, and the same being formed on arcs of a circle, concentric withthe axis of movement which is the shaft 34. Formed'integral with'thelower portion of each segment is an upwardly and forwardly curved arm39, the same carrying a series of spring held type or printing members40, the faces of which bear thecharacters from zero to 9 inclusive.

Formed on the underside of each curved arm 39 is a shoulder 41.Positioned immediately in front of the shaft 34 and the segments thereonis a transversely disposed I platen 42 around which is adapted to pass aweb of paper 43 as it unwinds from a spool or spindle 44. This spool orspindle is suitably positioned immediately in front of the housing 10and the web of paper passes through a suitable opening in the housingand around suitable, supports before reaching the platen.

A paper guard 45 partially surroundsthe platen, said guard beingprovided with an aperture 45 through which the printing members or typeare moved to contact with the surface of the paper. Fixed on one end ofthe platen 42 is a ratchet wheel 46 which is engaged by a spring heldpawl 47, the latter being carried by a disk 48 which is loosely mountedon the end of the platen spindle. This disk carries a pinion 48 which isengaged by the teeth of a segment 49, the latter being fixed on theshaft 34. Thus as the shaft 34 is rocked, the'segment 49 imparts partialrotary movement to the platen through the pinion 48*, ratchet wheel 46,and pawl 47.

Loosely mounted in suitable bearings in the lower front portion of thehousing is a shaft 50, the right hand end of which extends to theexterior of the casing 10, and fixed on said extending end is a crankhandle 51. Fixed on this shaft 50 within the housing is a crank arm52,-and pivotally connected to the upper end thereof is the forward endof a link 53 and the rear end of this link is pivotally connected to thelower end of a crank arm 54, which is fixed to the shaft 34. Looselymounted on this shaft 34 adjacent to this arm 54 is a bell crank 55, theshort arm of which carries a pin 56, which is normally positionedimmediately behind the upper portions of all of the segments 35.Attached to the other arm of this bell crank is a pin 57 to which isconnected the lower ends of retractile coil springs 58, the upper endsof which are attached to the upper portions of the segments 35.

' Arranged immediately beneath the shaft I 12 is a shaft 59 to which isfixed a crank arm 60, and pivotally connected to the lower end thereofis a link 61, the forward lower end of which is pivotally connected tocrank arm 54.

Fixed on shaft 59 is a segment 62 in which is formed an eccentric or camslot 63, which receives a roller 64, the same being jonrnaled on theside of a crank arm 65 which is fixed to shaft 12. Positioned on thebase of the machine in the lower front portion of the housing is a pairof upright plates 66, and arranged in the rear upper portion thereof isa shaft 67 on which is loosely mounted a series of hammers 68, therebeing one hammer for each segment 35, and the heads of said hammers areadapted to strike against the rear ends of the printing mema bers 40 tomove the same through their bearings in the curved arms 39 to causetheir forward ends to strike against and print upon the strip of papercarried by the platen 42. The lower ends of these hammers 68 areprovided with lugs 69 which are normally engaged by hooks formed on thefor ward ends of detents 70, the same being loosely mounted on a rod 71,the ends of which are seated in the plates 66, and the rear ends ofthese detents are provided with lugs 72 which normally rest on the,outer edges'of the curved arms 39 immediately adjacent to the shoulders41 thereof.

Connecting each detent with its correspondin hammer is a retractilespring 73, and fixed on the shaft 67 to the sides of the hammers 68 isapair of short arms 74, the upper ends of which carry a rod 75, whichoverlies all of saidha-mmers.

Fixed to the right hand'end of shaft 67 is a short crank arm 76, towhich is pivot ally connected the lower end of'a link 77, the u per endof which is pivotally connecte to crank arm 54. Journaled in the upperfor-ward corners of the plates 66 is a shaft 78, and fixed thereon is aseries of hammer detents 79, the hooks on which normally engage hooks 68formed on the rear sides of the heads of hammers 68, thereby holdingsaid hammers in their retracted positions. Fixed on the right hand endof this shaft is a depending finger 80 and connected thereto is one endof a retractile spring 81, the opposite end of which is connected to apin 82, which projects from the right hand oneof the plates 66. Fixed onthe shaft 50 is a short crank arm 83 to the upper end of which ispivotally connected the forward end of a link 84 in the rear portion ofwhich is formed a slot 85 provided at its forward end with a dependingnotch 86 and at its rear end with a.rear-. wardly extending notch 87.

' Arm 83 is provlded with a depending extension 83 and arranged betweenthe end mally occupying the forward end of slot 85 in link 84.

The forward end of lever 91 is provided with a laterally projecting pin93, which normally occupies the lower end of a slot94 which is formed ina vertically disposed link 95, the lower end of which is pivotallyconnected to a bracket 96 on the base of the housing. The upper end ofslot 94 is provided with a rearwardly projecting notch 97 which isadapted toreceive pin 93.

A retractile spring 98 connected to link 95 and one of the plates 66normally pulls said link 95 forwardly and maintains the same in positionseen in Fig. 1. A retractile suitable opening in the front wall of thehousing, and said forward end carries a disk or key 102.

Formed on the upper side of the lever 101 and near the forward endthereof is a I spring held detent 105'provided on. its front pair ofstop lugs 103 and 104 and adapted to a engage therewith is the lower endof a 25 side with a lateral projection 106. "This. projection is adaptedto be engaged by the, end of an arm 107 which is fixed to the shaft 50when said shaft is rocked to its forward" limit of movement by the crankhandle j 17 i Pivotally connected to the lower portion of arm 95 is therear end of a horizontally disposed lever 108, the rear portion of whichcarried out, this lug does not engage with overlies the rod 100 and therear end of this lever normally occupies a position immedilower end ofarm 83 is a lug 109 which is adapted to engage the rear end of lever 108when the: same has been elevated during a certain operation of themachine, but normally, or when the adding operations are the rear end ofsaid lever.

A pin or screw 110 is seated in the lever 101 and passes through a slot111 formed in lever 108. Pivotally connected to the rear end of lever101 is a vertically disposed spring held detent 112 which normallyengages beneath the rear portion of link 84 and formed in the undersideof said link beneath the slot 83 is a shoulder 113 against which theupper end of detent 112 is adapted to engage.

90 is a shaft 114 on which is loosely mounted a pair of upright members,one of which is provided with a depending portion 116, and seatedtherein is a pin 117 which normally occupies the lower end of a shorteccentrically curved slot 118, which is formed in the lever 91.

'Journaledin the upper ends of the members 115 is a shaft 119,'andloosely mounted thereon is a series of pinions 120, the samecorresponding to the toothed "racks 38, and each pinion being providedwith ten teeth. Each of these pinions is provided with a short laterallyprojecting pin 121. Arranged for vertical movement-to the rear of thesepinions is acorresponding series of plates 122, and formed in thefrontsides thereof are teeth 123, which are adapted 'to mesh'withthe'teeth'of pinions 120. Connected to theseplates and adapted to hold'a rod 115 carried by the arms 115 is a retractile spring 127, andformed on each secondary plate 125 is a lug 128 which normally engagesagainst a horizontally disposed rail .129, the same being arrangedbetween the vertical plates and the members 115.

Mounted on a shaft .130 to the rear of the upperends of the platesv 122is a. pair of forwardly extending arms 1131, the forward ends ofwhich-"carry a ro'd132, which normally bears upon the upper end of sa dPositioned above and to the rear of shaft plates122. Pivotally connectedto one of the arms 131 is the lower end of a link 133,

'the upper end of which is provided with a slot 134 in which engages apin carried by a short arm 135, which latter is fixed on shaft 59.

The operation of-my improved machine is as follows: Under normalconditions the various parts of the machine occupy positions seen inFig. 1, and as the scale with which my improved adding machine isassociated, is operated, the notched rings are partially rotated,thereby bringing certain of the notches of said rings into positiondirectly above the pins 16 on the forward ends of arms 15. It will beunderstood that prior to the movement of the notched rings, the rod 19is shifted lengthwise during the weighing operation so as to shift thehub 14,and the arms 15 upon the shaft 12 so that the pins 16 areproperly positioned relative to a certain set or series of notched rings11. To add and print the amount set up on the setting up mechanismwhich, in the present instance, comprises the notched disks 11, theoperator engages the crank handle 51 and pulls the same forwardly anddownwardly, thereby partially rocking shaft 50 and moving the arms whichare fixed thereto. As arm 52 moves forwardly link 53 connected theretoactuates arm 54 and shaft 34 is partially rotated. This movement also istransmitted through link 61 to arm 60, thereby partially rotating shaft59 and the segment Bell crank 20 which is fixed on shaft 12 iscorrespondingly elevated, thereby "raising pin 21 and permitting thethree arms 15 to move upward under the influence of retractile springs23. The pins 16 on the forward ends of these arms engage in the notchesof the three rings 11 immediately above said arms, and assuming thenumber set up by disks 11 to be 120 then the teeth of the first armoccupy the first notch in the hundreds disk. The second arm occupies thesecond notch in the tens disk, while the pin on the third arm occupies aposition against the edge of the units disk. As the arms are thuselevated, the fingers 17 engage against corresponding fingers 26 of theframes 25, thereby differentially elevating said frames andcorrespondingly differentially elevating the arms a, b, and c of theseries 27. As these arms are elevated the shoulders 28 on the undersidesthereof are raised to different distances with respect to the teeth 37of the three corresponding segnients'35, and thus the-segmentcorresponding to the hundreds, will be permitted to move the distance ofone .tooth, the second segment corresponding to tens will be permittedto move a distance of two teeth, while the third arm will not be ele,

vated an appreciable distance, thereby holding the third segment againstmovement, and which operation gives a result of zero in the subsequentoperations. As shaft 34 was partially rocked by the initial movement ofthe handle 51, bell crank 55 will be actuated thereby moving pin 56 awayfrom the rear sides of the segments 35, such action expanding springs 58and creating tension therein.

The first three segments will be partially rotated upon the shaft 34 soas to bring the corresponding teeth 37 into engagement with theshoulders 28 of the arms 27.

It will be understood that the teeth 37 of the segments are eccentricwith respect to the axis formed by the shaft 65, and for this reason theshoulders 28 will act as stops to engage theteeth of the segments as thesame are actuated.

As handle 51 is actuated, crank arm 83 and link 84 are drawn forward andjust prior to the end of the stroke of the handle 51,'the shoulder atthe end of slot 85 will engage pin 92, thereby swinging lever 91 uponits fulcrum, which is the shaft 90, and as a result pin 117 will bemoved rearwardly a slight distance, thereby actuating the framecomprising the uprights 115 so that the shaft 119 carrying the pinions120 will be moved forward so that said pinions are brought intoengagement with the teeth of the curved racks 38. .As the handle 51 is areturned to its normal position, the various parts just referred to,will return to their normal positions, and in so doing the teeth of thecurved racks 38 will impart partial rotary movement to the pinions 120,thereby adding into or accumulating therein, the amount set up on thenotched rings 11. Immediately prior to this return movement of thevarious parts, and after the segments 35 have been actuated asdescribed, the printing of the amount set up and added by the machine isaccomplished in the following manner. As the segments reach their limitof movement the rear ends of the detents pass beyond thesho-ulders 41 onthe curved arms 39, thereby disengaging the hooks on the forward ends ofsaid detents from the lugs 69. As arm 83 reaches its limit of movement,lug 89 thereon strikes against the lower end of finger 80 therebypartially rocking shaft 78 and releasing the pawls 79 from the hooks 68*on the hammer heads. The tension of springs 73 now actuates the hammersand the heads thereof move upward with a quick motion, and strike therear ends of the printing members 40 which have been moved into positionimmediately in front of aperture 45, and as a teeth of pinion 48", whichlatter is connected to disk 48 carrying the pawl 47, and which latterengages with the teeth of the ratchet wheel 46 carried by said platen.As the handle 51 is returned to its normal position the various parts ofthe adding and printing mechanism just described return to their normalpositions. The pinions 120 act as accumulators inasmuch as the differentamounts set up and added into the machine are accumulated during thesuccessive operations, and as the first pinion makes a completerevolution, that is, ten teeth, the pin 121 carried by said wheel willstrike against the inclined or rounded forward end of the adjacentfinger 126, thereby swinging the upper end of auxiliary plate 125rearward to release lug 128 from rail 129. This releasing movement takesplace while the pinions 120 are in mesh with the teeth of racks 38, andas soon as such release takes place, plates 125 and 122 are drawn upwardunder the influence of spring 124. The length of upward movement of theparts 122 and 125 corresponds to one tooth of the pinions, and when saidpinions have swung backward to normal position, they rengage with theteeth 123 and the parts will now be in position to transfer from thefirst pinion to the second or third, as the case may be. When the firstpinion has made a complete revolution and a transfer is made to thesecond pinion, a total of 10 is set up in the accumulators, and when thesecond pinion has been rotated a complete revolution a transfer is madeto the third pinion, thereby setting'up 100 in the accumulators. Theplates 122 and 125 move upward only when rod 132 is elevated, whichaction is brought about by means of link 133 which is elevated by arm135 on shaft 59 and owing to the slot 134 in side link, the rod 132 isnot raised until after the shaft 59 has been partially rocked and thepin carried by arm 135 reaches the upper end of slot 134.- When shaft 59rocks back to its normal position, link 133 is moved downward therebymoving rod 132 downward and as a result the plates 122 which wereelevated, will be moved downward the distance of one tooth, and as aresult, the engaged pinions will be rotated a distance of one tooth, andconsequently transferring from one pinion to another and accumulatingthe total in said pinions.

To obtain a total of all transactions, as for instance, at the close, ofa days business, the operator -depresses the forward end of lever 101 byengaging key 102, and as this movement takes place the detent 105 passesfrom shoulder 103 to shoulder 104, thereby locking said lever in itsdepressed position. As the rear end of this lever is elevated, the pawl112 raises the rear end of lever 84 until the pin 92- is engaged .bynotch 86. The op of the teeth 37 on the segments.

erator now engages handle 51 and pulls the same forwardly and downward,and following the initial forward movement of link 84, the lever 91 willbe rocked upon shaft 90, as a result of the .engagement of pin 92 bynotch 86. As a result, the rear end of lever 91 will be depressed andthe forward end will be elevated, and said lever will be locked in thisposition by the engagement of pin 93 in notch 97 As the rear end oflever 91 is depressed pin 118 will be engaged to move the members 115forwardly, thereby bringing the pinions 120 into engagement with theteeth of racks 38. As the rear end of lever 101 is elevated link 33will-be likewise elevated, thereby partially rocking shaft 29,

and as a result the arms carrying rod 31 will be slightly elevated,thereby elevating the free ends of arms 27 so as to move the shoulders28 out of the path of travel The continued movement of the handle 51actuates the segments in the manner hereinbefore described, and the sameare shifted to various positions by reason .of their engagement with thepinions 120, and which during this movement, are reversely rotating totheir a home or zero positions with the pins 121 in position beneath thefingers 126, This movement positions the proper printing members 4:0 infront of the opening 45 and as the hammers are actuated in a mannerheretofore described,- the proper printing members are struck to printthe total of all the transactions upon the paper carried by the platen.The final movement of handle 51 brings the end of arm 107 intoengagement with lug 106, thereby moving the detent 105 off the shoulder104 to release lever 101 and at the same time lug 109 strikes theforward end of member 108 to move the same re arwardly, thereby rockinglever 95 so as. to unseatpin 93 from notch 97 thereby permitting spring99 to restore lever 91 to its normal position. Thus the pinions 120 aredisengaged from racks 38 and reengaged with the teeth on the plates 122.During the taking of totals and immediately after the initial movementof link '84 to. engage pin 92 to rocklever 91, the forward'movement oflever 84 will bring the notch 113 opposite the upper end of detent 1112, and thus the rear end of link 84 will dro a short distance, therebyunseatingpin 92 rom notch 86, and as the movementof handle 51 iscontinued pin' 92 will travel through slot 85 and pass into theextension or notch 87 without further affecting lever 91. On the reversemovement of link 84, the upper edge of slot 85 bears, on pin 92 so thatthe rear .end of said lever is restored to its normal position upon pawl112. Y

A computing and listing machine of my improved construction iscomparatively simple, is particularly adapted for use in the necessaryoperations for adding various amounts, accumulating the total thereof,and printing the individual amounts and likewise the total thereof.

It will be readily understood that minor changes in the size, form andconstruction of the various parts of my improved computing and listingmachine may be made and substituted for those herein shownand described,without departing from the spirit of my invention, the scope of which isset forth in the appended claims.
